System Surveillance via SNMP

The system state of an OnAir

console can be optionally monitored

via SNMP messaging. The Simple

Network Management Protocol

is a common method to monitor

and control networked devices

independent of type and usage.

The way SNMP is implemented enables

two different methods of receiving

information from a single or multiple

OnAir systems in an IP network.

Systems can actively send important

status information to the connected

network. Special messages (Traps) are

triggered when parameters reach or

surpass predeﬁned thresholds, e.g. a

processor’s temperature has risen to

a critical level, or a console’s ‘On Air’

state is activated. Additionally, traps are

sent on any occurring system alert, e.g.

PSU error or synchronisation switch-

over. Such active sending does not

need any user interaction.

For surveillance issues, users can

also request the current status

information of system parameters

(Polls). This is possible at any time

and independent from status and

parameter. Thresholds for traps can

be conﬁgured in a corresponding

XML ﬁle for each console.

To view SNMP messages from an

OnAir system, customers can use

any third party SNMP manager

software on the market. Usually, such

applications combine viewing, logging

and ﬁltering functionality with useful

features like sending a notiﬁcation

email when a speciﬁed trap occurs.
